I think we can mark this one as "Nothing to do" (in this patch or a follow-up), AFAICS it doesn't affect the implementation.

Let's mark any NFCs as separate patches.

I pinged some folks on some LWG issues, it would be nice if you could have a look when you have some time.

@huixie90 This is your paper I think

I had a look at the issue and see only removals. I still think it's good to validate whether these lessened restrictions are something we can/want to take advantage of in libc++. Since this is not my area of expertise I prefer to leave it open so a you or another ranges expert can decide whether or not to close it with nothing to do.
